morphometric characteristics of anticlines can play an important role in the exploration of oil resources. the purpose of this research is to evaluate the effect of geomorphology on the exploration of oil resources in oil-rich bankol and oil-less danehkhoshk anticlines by means of geomorphological indices. to achieve the purpose of this study, topographic maps at a scale of 1:50000 and geologic...

nesar anticline is located in west of country and in north of kermanshah province. pattern of drainage network at each district is under the effect of various factors which has intensive anomaly in nesar anticline in spite of its low area and this in turn reflects different lithology, tectonic effects and slope changes in anticline. the goal of this research is the recognition of influential fa...

In this paper, we introduce a new approach for fitting of a bounding rectangle to closed regions. In this approach the coordinates of the vertices are computed directly using a closed-form solution. This approach is based on simple coordinate geometry and uses the boundary points of regions. Using a least-square approach we determine the directions of major and minor axes of the object, which g...

China is a country with vast territory, but economic development and population growth have reduced the usable land resources in recent years. Therefore, reclamation by pumping and filling is carried out in eastern coastal regions of China in order to meet the needs of urbanization. However, large areas of reclaimed land need rapid drainage consolidation treatment. Based on past researches on h...

In many industrial and non-industrial applications, it is necessary to identify the largest inscribed rectangle in a certain shape. The problem is studied for convex and non-convex polygons. Another criterion is the direction of the rectangle: axis aligned or general. In this paper a heuristic algorithm is presented for finding the largest axis aligned inscribed rectangle in a general polygon. ...

In this paper, we introduce the notion of an (a, b)-rectangle pattern on permutations which is closely related to the notion of successive elements (bonds) in permutations and to mesh patterns introduced recently by Brändén and Claesson. We call the (k, k)-rectangle pattern the k-box pattern. We show that we can derive an explicit formula for the number of permutations of Sn which have the maxi...

In document processing, segmentation is done to uniquely identify each foreground connected region of an image by specifying its minimum containing rectangle (MCR). MCR is the rectangle with minimum dimensions that completely encloses a geometric pattern. In this paper, we present a two-step MCR detection algorithm and its parallelization method. The first step determines the boundary of each c...

abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...
